4 v Edward Porter, Akron,

twentieths to Alvin W Ohio, assignor of' two` Larson, Akron, Ohio Application July 23, 1943, serial No. 495,907 8` Claims. (Cl. 280-28) 'I'his invention relates to ski'runners and has relation more 'particularly to devices of this kind especially designed and adapted for use with 'vehicles of a power driven type and it is a primary object of the invention to provide a ski runner of a type to facilitate the travel of a vehicle over a deep snow terrain. Y

It is 4also Aan object of the invention to provide a ski runner with means at its forward portion to facilitate passage through a snow drift and wherein the rear or heel portion of the runner is provided'with 'means to-facilitate backing up of the runner. 1 v A still further object of the invention is to provide a ski runner which is light inweight but constructed in a manner tol assure requisite strength. i i y.

An additional object ofthe invention is to provide a runner of. this kind including effective means to prevent side slippage or lateral skidding to assure straight ahead travel over a snow terrain.

.The'invention will best be understood from a consideration of the following detailed descriptiontaken'in connection with the accompanying drawing,-it being understood, however, that the invention is not to be considered as limited by the specic'. illustration or description but that such illustration and description constitute a preferred embodiment of the invention.

In the drawing:

Figure 1 is a view in side elevation of a ski runner constructed in accordance with an embodiment of the invention;

Figure 2 is a sectional view substantially on the line 2 2 of Figure 1, looking in the direction l of the arrows:

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure ,1, looking in `the direction of the arrows;

Figure 4 is a transverse sectional view taken through a ski runner constructed in accordance with another embodiment of the invention.

In the embodiment of the invention as illustrated in Figures 1 to 3 of the drawing, l denotes an elongated runner preferably of a light weight over a snow terrain thereof is disposed upwardly on a short radius -to provide a heel 3 to facilitate backing up of the runner and more especially when the snow terrain is deep.

or plate 8 overlap,

The side or longitudinal marginal portions of the runner I are provided with the upstanding flanges 4 which serve to strengthen or reinforce the runner l vand these flanges 4 extend from the extreme front end of the runner l to the extreme rear end thereof. Y

At required points intermediate the ends thereof the flanges 4 are provided with the upstanding bracket plates `5 or ythe like to provide means whereby the ski runner-is'operatively applied to the vehicle with "which itisto be employed. As the mounting of the ski runner forms no part of the present invention, a detailed-description and illustration of such a mounting is not. believed necessary. v .i i

The, runner i has pressed therefrom oiuotherwise formed the transversely spaced ribs 6, shown as two in number. and which extend lengthwise of the runner l lfrom points forwardly `of the longitudinal center of the runner l to the.A heel 3. VEach of these ribs, as herein comprised, is yV-shaped in cross section at all points therealong with the apex thereof downwardly directed and as is .illustrated in Figure 1 ofthe drawing, each of the ribs continuously `increases in depth from il at its forward end to a point closely adjacent to the heel 3.

vResting upon the runnerl and extending from substantially one end to the other are the. rein-4r forcing members 1 of light weight steel alloy or other comparatively light material. These members 1 are L-shape in cross section with their foot anges a contacting the runner l and their leg flanges b upwardly disposed. As herein embodied, the leg flanges b of adjacent members 1 abut and the sum of the lengths of the foot anges a equals the space between the flanges 4.

The upper edges of the leg flanges b of the members 1 are substantially hush with the upper edges of the flanges 4 of the runner l and disposed over the runner l and resting from above on the upper edges of the legs b of the members 1 and the upper edges of the flanges 4 is a cover sheet or plate 8. This sheet or plate 8 is of a l alloy or other equally light weight material and is preferably of slight thickness. The side marginal portions of the sheet as at 9, the outer face of the upper portions of or otherwise secured. l

The forward end portion of the sheet or plate 8, or that portion overlying the forwardly upwardly disposed portion standing blade I0, which provides means to facilithe flanges 4 and are welded.

2 of the runner I. is provided at its transverse center with an upt Resting-.upon the.. l extending light were tate travel of the runner should the same penetrate a ysnow drift or the like. As is clearly shown in Figure 1 of the drawing, the upper or working .edge c of this blade I is arranged on an upward curvature. Y

To facilitate raising of the forward portion of the runner I when in a snow drift or the like and to prevent packing of snow along opposite sides 0f blade. there are previded at eppesite sides of the blade II! the downwardly and ont:

`Wardly curved aprons or plates I I, These aprons `or plates II are prefereably ofY thin light metal' `and Welded into place and such aprons or plates I I extend outwardly and laterally from the blade 1 I0 at a point materiallybelow the upper Aor work.- ing edge c of the blade.

In the embodiment of the -invennqp @s inns,

trated in Figure 4, the runner` I2 at itstransv'erse center is provided with a single depending rib `which serves as a rudder or stabilizing element ibs el the first. embodiment nner i12. are the longitudinally ht alloyst .l .tenes I.5.shown the dame as the r desired manner as indicated at IL Lclaim:
